ROLLER-CGASTER SKTE.

To .all whom/'it may concern Be it known that l, JOHN CRITTENDEN Tn'r'r, a citizen of the United States, resid.- ing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Rollern Coaster Skates; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will en` able others skilled in the art to which it appertains to make and use the same.

`My invention has for its object to'provide an improved roller coaster skate, and to such ends, generally stated, the inyention consists of the novel devices and combinations o'l devices hereinaterdescribed and defined in i f the claims.

Hitherto, roller-coaster skates have been made'by applying the rollers of roller skates to small foot platforms and in providing' the platform' with handles rising from the front ends thereof. The rollers employed in, my improved coaster are also preferably of the roller skate type.

As one feature othis invention, in addition to applying two pairs of rollers, one. ahead of the other, I apply a third pair at a point laterally odset from, but midway between the longitudinally alined pair of rollers.`

l As another feature of the invention, instead of applying the hand piece or handle at the front end ofthe foot platform, l

apply the same at one side thereof. This handle is preferably inthe form of a bail or inverted lil-shaped rod, the lower ends of which are bent laterally and secured to the lio bottom of the platform, so that they rein- `force the same, and the' upper portion of which is adapted to be conveniently gripped by the hand, so that the platform may be held firmly to the foot even wn. the foot is raised.

Another feature of the invention isound in the brake which is arranged "to be oifierated by stepping on the same, and which operates on one or more of the wheeler.i

ln the accompanying drawings which illustrate the invention, lilre characters in dicate like parte throughout the several views.

Reterring to the drawings: Figure l is a `View in side elevation showing the improved nollercfoaster skate;Fig. 2 is a reer elevation of the same; and Fig. 3 is a horizontal section taken on the line w8 :es op Fig. 'l'.

Speclcation of Letters Patent.

The vso-called foot platform 1, prefer ably constructed, is provided with an Patented May d, 1915.

case. rlhe platform l; is supported by three small two-wheeled trucks which may be, and preferably are, of the identical type found on roller skates. trucks, it is only necessary -to particularly note the wheels 3, axles Il, axle bearing brackets 5 and anchoringbrackets 6. The anchoring brackets 6 are riveted, or other wise rigidly ysecured tothe platform 1. The brackets 5 and. 6 are pivots ly connected by oblique pins 7, andthe said brackets 5 and 0f the parts of these G are yieldingly held in intermediate posiy tion by spring devices not shown, but which may he such asvfound in roller skate construction. However, in some instances, l may employ trucks that are not yielding and may, in some cases, employ three onewheeled trucks, 'or simply three wheels disf posed irhe relative arrangement above noted rlhe brake 8 is preferably constructed l from a ythin bar of spring steel, one end of which is attached to the bottom of the platform l, one end of which extends upward through al keeper 9 on. the rear end of the platform, and the intermediate portion of which vis curved so that it will engage and' closely tit the underlying truck wheel. The' spring' tension of the brake bar or lever 8 is such that, normally, it is heldout o conico tact with the truck wheel, butmey bepressedi against the said truclfwheel'y when the rear upper' end thereof is steppedupon by the' heel, or other portion of the-floot applied on the platform.

rlhe numeral 10 indicates a pleteor board applied between the legs of the bail 2, and; as shown, secured thereto, by clips 1l. This board l() will conveniently serve as an ed` vertising board upon which. advertising mati ter may be printed, or otherwise applied.

' lt lie important to note that the hoard l0 IGS terminates helovv the top of the hail-like handle, soa-s to leave a space through vv hich the hand or l'ingers may he passed for gripping the upper portion ot the said handle.

The coaster shown is intended to housed with the right foot, leaving` the left foot free for engagement with the side walk or floor, over which the coaster is run. The Ilisposition of the hail-like handle at one side, to-wit, at the outer side of the foot, permits the upper portion thercotl to he cngagefl. by the right hand, without throwing^ the body out ot its naturalposition, and nrtlierniore, permits, as already indicated, the platform to he hold against the vfoot when the foot is raised.

The triangular oli'set disposition ot the rollers gives lateral stability to the coaster, so that it will not easily tip over. At the Sametime, by tilting the device from one side to the other, it may he steered. This steering action is d ue to the reversed ohliqne arrangement of the pivot pin 7, and is an action .which takes place in roller skates.

As a possible modification of the device within the scope of my invention, I would suggest that a platform with a laterall7 on?- set handle might he used in connection with a skate runner applied to the iniderside ol the said platform.

What l claim is:

1. A coaster comprising a plat'torn'i having a support permitting' it to travel and provided with a `bail-like handle ol'l'set at one. side ol the intermediate portion thereof, rising ahove the same, and having thc lower ends of its lient horizontally and secured to said platform.

2. A rollei` coaster comprisingr a platform, rollers in triangular arrangen'ient supporting said platform, and a handle seein-ed to one side of said platform and rising from the intern'iediate portion thereof.

8. A roller coaster comprising a platform, rollers in triangular arrangement supporting the same. and a hail-like handle offset from one side ot' the intermediate portion of said platform having' the lower ends of its legs lient horizontallykxnd rigidly secured
